Abstract

The utility model discloses a solid particle material separating device, in particular to a vibrating screen mesh comprising a screen strip and a frame beam, characterized in that frame beam section is a rectangular and circular tube, a doff proof rod is provided under the screen strip, a conical abrasion-proof screen strip is employed, the rear portion of the screen strip mandrel crosses the screen strip hole, tightens and twists, welding and filling charges methods are employed to integrate the screen strip and the frame beam. For vibrating screen, the screen strip front end is low while the opening is big, the rear end is high while the opening is small, moreover the surface is smooth, material slides along with vibration smoothly and is blocking proof, thereby the screen face is cleaned automatically, in particular to the rear end of the screen strip is welded and filled with charges, the screen strip and the frame beam are firmly communicated. The utility model has the advantages of rational structure, simple manufacturing engineering, low cost, convenient maintenance, not only automatically cleaning the screen strip, but also corrosion prevention, improving separating efficiency.

Description

The wear-resisting comb teeth shape screen cloth of self-cleaning

Technical field

The utility model relates to a kind of solid particle material screening plant, the especially screen cloth of being made up of grating, set a roof beam in place etc., sieves to contain the granule materials wet, hard, that corrosion is arranged.

Background technology

In industries such as metallurgical, mine and building materials, extensively adopt rod formula vibratory sieve, solid material is sieved, particularly to containing wet and the screening of the material of corrosion is arranged, compass screen surface jam putty has a strong impact on the screening efficiency of vibratory sieve.In the prior art, Chinese utility model patent 98243768.4 is set up a covering device and is solved the putty problem, but makes complexity, cost height; Grating easily becomes flexible, comes off, and it is fragile to be impacted the position, also reduces screening efficiency.Patent Office of the People's Republic of China's invention disclosed patent 98110435.5, suit wear-resistant block outside the grating muscle fills between grating muscle and the wear-resistant block with adhesive or elasticity overcoat, such grating is a right circular cylinder, and between two gratings, the front and back end is equidistant, material folding easily, wear-resistant block both ends of the surface projection particularly, two adjacent wear-resistant block joint areas just form annular recess, easier material folding, be difficult to come off, follow-up material is cumulative, causes large tracts of land stifled, influences the screening efficiency of vibratory sieve; Also has complex manufacturing technology, the cost height.

Summary of the invention

The purpose of this utility model provides a kind of used by oscillating screen screen cloth, can simplify the grating structure, reduce cost, and wear-corrosion resistance is arranged again, more can clear up compass screen surface automatically, improves the bolting operating rate.

The wear-resisting comb shape screen cloth of a kind of self-cleaning, mainly form with setting a roof beam in place by grating, the two side symmetry of setting a roof beam in place is equidistantly offered a plurality of gratings hole, the grating hole is passed in the rear end of grating, be fixed on set a roof beam in place on, front end is unsettled, its feature in: set a roof beam in place and adopt the cross section, the fixedly anticreep rod of grating is set at grating hole downside for apart from shape or circular body; It is conical that abrasion-resistant grate bar is, and the grating hole is passed in the rear end of its grating plug, strains, twists and warps and be welded on a side of anticreep rod; Fixedly the charges of grating are modulated into liquid state, are poured in the tube chamber of setting a roof beam in place, and are encapsulated in the two ends of setting a roof beam in place with shrouding, will set a roof beam in place and intraluminal grating plug solidifies in aggregates.The screen cloth that constitutes like this, the distance between adjacent two gratings, the little front end in rear end is big.This screen cloth is installed in level to be had on the vibratory sieve at certain inclination angle, and rear end height and opening is little is preceding low and opening is big, be one horn-like, and smooth surface, the material of screening is along with the smooth and easy downslide of vibration meeting of vibratory sieve, even material has temporary transient quilt to press from both sides, along with the vibration of vibration sieve nest, grating vibrates thereupon, adds the impact that material falls, and the clipped object material also can come off very soon, thereby need not to add beating unit, just can clear up compass screen surface automatically.Particularly grating is through welding and perfusion charges, grating with set a roof beam in place connect solid firm; This scenario-frame is reasonable, manufacture craft is simple, cost is low, has both had the function of automatic cleaning compass screen surface, and wear-resisting, decay resistance is arranged again, has improved screening efficiency.

The specific embodiment

As can be seen, the utility model employing cross section is that the body of rectangle is set a roof beam in place (2) from accompanying drawing, and (2) the one end shutoff of will setting a roof beam in place earlier according to the screening requirement, are offered the grating hole (3) of the identical equidistant arrangement in a plurality of apertures on set a roof beam in place (2); In order to reinforce grating (1), downside is provided with anticreep rod (5) in grating hole (3), firmly is fixed on set a roof beam in place (2).Abrasion-resistant grate bar (1) is made up of grating plug (7) and wear-resistant protection cover (9), elastic washer (8), (10), is conical.Grating plug (7) is the spring steel rod of the thick head of front end band big and heavy stone (11); Wear-resistant protection cover (9) is a center ceramic circular cone stage body with holes, and two ends are provided with the infundibulate groove, for fastening and increase rod elasticity, is provided with elastic washer (10) between two wear-resistant protection covers (9); Elastic washer (8), (10) center are with holes, a side band conical protrusions and both sides are arranged all with two kinds of specification packing rings of conical protrusions, and during use, elastic washer (10) conical protrusions matches with the infundibulate groove of wear-resistant protection cover (9).During the assembling screen cloth, successively a plurality of elastic washers (10) and wear-resistant protection cover (9) are contained on the grating plug (7), the conical protrusions and wear-resistant protection cover (9) the infundibulate groove of elastic washer (10) are complementary, and the diameter of the end of two wear-resistant protection covers (9) of joining is consistent before and after making, and puts the elastic washer of using the rear end (8) again; Again the rear end of grating plug (7) is passed grating hole (3) tension, twist and warping, and a side (6) that is welded on anticreep rod (5) is located, for preventing that grating (1) from becoming flexible, coming off, the cement mortar that to become reconciled is poured in the tube chamber of set a roof beam in place (2) again, condense into piece (4), to pour into the also shutoff of this end of charges at last, and be about to set a roof beam in place (2) and intraluminal grating plug (7) is solidified as one.

Charges also can be used rubber, resin, plastics etc.; The material of wear-resistant protection also can have cast stone, glass, carbon steel and in surperficial cure process.
